Description

Updated bind packages that fix one security issue are now available for Red
Hat Enterprise Linux 5.

Red Hat Product Security has rated this update as having Important security
impact. A Common Vulnerability Scoring System (CVSS) base score, which
gives a detailed severity rating, is available from the CVE link in the
References section.

The Berkeley Internet Name Domain (BIND) is an implementation of the Domain
Name System (DNS) protocols. BIND includes a DNS server (named); a resolver
library (routines for applications to use when interfacing with DNS); and
tools for verifying that the DNS server is operating correctly.

A flaw was found in the way BIND handled requests for TKEY DNS resource
records. A remote attacker could use this flaw to make named (functioning
as an authoritative DNS server or a DNS resolver) exit unexpectedly with an
assertion failure via a specially crafted DNS request packet.
(CVE-2015-5477)

Red Hat would like to thank ISC for reporting this issue. Upstream
acknowledges Jonathan Foote as the original reporter.

All bind users are advised to upgrade to these updated packages, which
contain a backported patch to correct this issue. After installing the
update, the BIND daemon (named) will be restarted automatically.
